Wanted to build the Vintagepcbkit u67. It is my first Mic build and i have no idea how to trouble shoot and have no mentor to ask. Hoping you guys could take a listen and give me ideas on where to go from here.
All psu B+ H- measurments are correct. They are also correct with the mic connected.
I have swapped tubes that i know are working because i tested them in my Lauten Eden.
I swapped a styroflex that i thought might have been the issue because i slightly burned the edge that had no effect.
I would not have picked such a difficult mic for my first build but i had no idea about Hi Z or plate voltages. All things considered i have learned alot with my failure so far. Any recommendations would be helpful.
Below is a recording so you can listen and theory craft.
Thank you
